Looking at some grocery stores online shopping sites, I had this idea about a service that delivers a CSV file listing all the price information from various grocery stores in a given area.
Users of the CSV might be people who shop at a variety of grocery stores, buy the same products periodically and want to know when these products are currently on sale.
The motivation is that a user might not want to shop only when her supply of a product runs low but more strategically when the price of a product drops.
There are certainly other ways offline and online to get this information but AFAIK not in a spreadsheet-friendly format that combines price info from multiple stores.
Of course there might only be one user: me. I have no idea if anyone else would see this as useful. It was an excuse to make more CSV to play with in kdb+.
